There are a variety
of websites that can shorten your long links, making simpler barcodes
(or making
long links easier to fit on Twitter). You automatically will
be redirected
to the longer URL. It's that easy!

QR codes are used in
both commercial tracking
applications and convenience-oriented applications aimed at mobile
phone users. QR codes can be used to display text to the user, to add a
vCard contact to the user's device, to open a URI or to compose an
email or text message. Users can also generate and print their own QR
codes for others to scan and use by visiting one of several free QR
code generating sites

QR codes storing addresses and
URLs may appear in
magazines, on signs, buses, business cards, or on just about any object
about which users might need information. Users with a camera phone
equipped with the correct reader application can scan the image of the
QR Code to display text, contact information, connect to a wireless
network, or open a web page in the phone's browser.

Google's mobile Android operating system supports the use of QR codes
by natively including the barcode scanner (ZXing) on some models, and
the browser supports URI redirection, which allows QR Codes to send
metadata to existing applications on the device. Nokia's Symbian
operating system is also provided with a barcode scanner, which is able
to read QR
codes, while mbarcode is a QR code reader for the Maemo
operating
system. In the Apple iOS, a QR code reader is not natively included,
but over 50 free Apps are available with reader and metadata browser
URI redirection capability.
